The Atlantic Rainforest at REGUA is well protected and expanding, and one of the prime habitat quality indicator species are amphibians. Are the populations stable or declining?
Researchers are always interested as their population numbers reflect air quality and air humidity levels, which in turn are affected by forest cover. There are over seventy amphibian species at REGUA and with programmes in forest protection and expansion, all species appear to be in good shape.
One genus that attracts attention is the Atlantic rainforest endemic Horned frog which we found on the green trail recently. Both Proceratophrys appendiculata (also known as Guenther’s Horned Frog) and Proceratophrys boiei were seen. They live in the leaf litter in forests up to an altitude of around 1200m, and spawn in forest streams.
Both species are relatively common at REGUA and all visitors like to pick them up and get a closer look at them. They sit immobile and looking rather glum, patiently waiting to be returned to the ground when they hop off into the leaf litter and are quickly almost impossible to refind.
